ROLLER-ian Aiuiverl Specification of Letters Patent.

Patented June 1, 1909.

Application led August 25,* 1908. Serial No. 450,170.

To all'whom it may concern; j

Be it known that I, ELIELL. SHARPNECK,

v,of Vinthrop, in the county of Suffolk and .State lof Massachusetts, have invented cer'-A tain new and useful Improvements in Roller- Bearings; and I herebyT declare that the following 1s a full, clear, and exact specifica- .ti'on of the saine, reference being had to,-

the accompanying drawing, forming' part thereof.'

`This invention has reference to improvementsinroller bearingsy and refers articularly .to the peculiar means whereby frictional resistance 'betweeninoving parts of the bearing is reduced.

One object of the invention is to im rove -theconstruction of the anti-friction rol s and the niountings therefor. Another object of the invention is to reduce .the frictional resistance between the ends of the rotating members and the stationary parts of the journal box.

-Other objects-of the invention will appear from the following description. j rlhe invention 4consists in such peculiar lfeatures of construction and combination of parts as shall hereinafter bedescribed andl pointed out'in the claims.v

Figure 1, represents a sectional View of the o/inproved'roller bearin shown asl applied to a journal box and in re ation toa shaft jourl'naled therein. Fig. 2,- represents an end view of the same with the journal box cover removed, parts of the bearing being broken away.

Similar numbers of reference 4designate corresponding parts throughout.

As shown in the drawings in itspieferred form 5 re resents a journal box iaving af cylindrica inner'wall-and furnished with the end 6 having the cylindrical opening 7. The openL end of said box is closed by the cover 8 having the pocket'9 furnished with i .the Wooden block 10 seatedin said pocket dept and referably ofathickness'less than the of, said pocket. W'ithiii the cylindrical way formed by the box 5 and at the l'ends thereof are secured the annular wooden antifriction collars 11 and 12. These collars, 11 and 12, as well as the block 10 are Saturated-with lubricant of any well known nature, preferably oil, and said collars have central openings to receive the shaft 13 one end of whichA is, received in the pocket 9 being free, in itsslight endwise movement,`

tate with comparatively little friction.

to bear against the block 10 which forms an anti friction thrust bearing therefor.

Mounted in the box 5 is a cage formed with a pair of annular metallic members 1'4-14 each having a series of sockets 15-15 lat their inner sides to closely fit theends of ythe-"metallic pins 16-16 which are driven through perforatiens in the anti friction washers 17-17 and into s aid sockets 15 -15 Qn said pins 16- 16 are journaled anti friction rolls which comprise outer tubularinetallic'members 18e-18 having driven therein the wooden bushings 19-'19 which are treated with anyv well known lubricant and have axial bores free to rotate'on the pins 16-16. In this structure the rolls 18-18 are free to rotate independently between the cylindrical way, formed by the wall of box 5, and the peripheryof the shaft 13 while' said rolls are held in valineinent by the pins 16-16 on which the bushingsflQ-lQ are free to roanti friction roller cage as a whole is free to revolve about the shaft 13 and any end thrust of the smooth outer surfaces of inem- .bers 14-14 of said cage is received by the anti friction collars 1212.

It is to be noted that by the driving ofthe bushing 19' into the bore of the roll 1S these parts are iirmly secured together against independent movement and the fibers of the bushing or sleeve 19 are somewhat conipressed. y

Having thus described my invention I claim as new and desire to secure byLetters Patent. The combination with a cylindrical casing having a' cover furnished with an axially disposed pocket, a wooden block in said pocket, a pair of wooden anti friction collars 'frictionally secured in saidcasing, and a cage rota.
